APPEOVED ANSWERS
A computer science student is studying intelligent agents. Which of the following best
describes a rational agent in artificial intelligence?
a. An agent that always follows pre-programmed instructions without deviation
b. An agent that maximizes its expected utility, given its current knowledge
c. An agent that mimics human emotional responses
d. An agent that operates without any sensory input
✔️ Correct Answer: B
Rationale: A rational agent is one that maximizes its expected utility given its current
knowledge. This definition is foundational to AI and emphasizes decision-making under
uncertainty. Option A describes a simple automated system without rationality. Option C
describes affective computing, not rational agency. Option D describes an agent without
perception, which cannot be rational.
,A researcher is translating information into symbols to facilitate inferencing. What is this
process called?
a. Natural Language Processing
b. Knowledge Representation (KR)
c. Machine Learning
d. Computer Vision
✔️ Correct Answer: B
Rationale: Knowledge Representation (KR) involves translating information into
symbols to facilitate inferencing from those information elements and the creation of
new elements of information. Option A (NLP) deals with human-computer language
interactions. Option C (Machine Learning) focuses on algorithms that improve with
experience. Option D (Computer Vision) processes visual information.
A scientist is designing a test to determine if a machine can demonstrate intelligent
behavior indistinguishable from a human. What is this test called?
a. Turing Test
b. Cognitive Test
c. Behavioral Test
d. Rationality Test
✔️ Correct Answer: A
Rationale: The Turing Test was designed to provide a satisfactory operational definition
of intelligence, where a machine's responses are indistinguishable from a human's.
Option B is a general term for cognitive assessment. Options C and D do not specifically
refer to the Turing Test.
A computer science student is defining artificial intelligence. Which of the following best
describes artificial intelligence?
,a. The study of human cognitive processes
b. The intelligence of machines and the branch of computer science that aims to create
it
c. The design of computer hardware only
d. The study of biological neural networks
✔️ Correct Answer: B
Rationale: Artificial intelligence is defined as the intelligence of machines and the
branch of computer science that aims to create it. Option A describes cognitive
psychology. Option C describes computer engineering. Option D describes
neuroscience.
A linguistics student is studying human-computer interactions. What field deals with the
interactions between computers and human languages?
a. Computer Vision
b. Machine Learning
c. Natural Language Processing
d. Robotics
✔️ Correct Answer: C
Rationale: Natural Language Processing (NLP) is a field of computer science and
linguistics concerned with the interactions between computers and human languages.
Option A processes visual information. Option B focuses on algorithms improving with
data. Option D deals with autonomous machines.
A data scientist is designing algorithms that allow computers to evolve behaviors based
on empirical data. What is this scientific discipline called?
a. Natural Language Processing
b. Knowledge Representation
c. Machine Learning
d. Automated Reasoning
, ✔️ Correct Answer: C
Rationale: Machine Learning is a scientific discipline concerned with the design and
development of algorithms that allow computers to evolve behaviors based on
empirical data. Option A deals with language. Option B deals with symbol
representation. Option D deals with logical deduction.
A robotics engineer is describing an autonomous entity that observes through sensors
and acts upon an environment using actuators. What is this entity called?
a. Algorithm
b. Intelligent Agent
c. Neural Network
d. Expert System
✔️ Correct Answer: B
Rationale: An Intelligent Agent is an autonomous entity which observes through
sensors and acts upon an environment using actuators, directing its activity towards
achieving goals. Option A is a step-by-step procedure. Option C is a machine learning
architecture. Option D is a decision-making system.
A mathematician is studying logical deduction. Which area of computer science is
dedicated to understanding different aspects of thinking?
a. Computer Vision
b. Machine Learning
c. Automated Reasoning
d. Natural Language Processing
✔️ Correct Answer: C
Rationale: Automated Reasoning is an area of computer science and mathematical
logic dedicated to understanding different aspects of thinking. Option A processes
visual data. Option B focuses on learning from data. Option D deals with language
processing.
